Rankers

Rankers are must-be-on-top Use Cases which should always apply (importance from top to bottom).
In general, it is not advised to use rankers for anything else than general ranking rules (e.g.: in stock first, ...)
Product Attribute Promoter : that's the standard case to create any ranker based on your product attributes (new products, a specific brand of products, ...)
Article-Based Repeater : only for up-sell and cross-sell tpo: create a matching ranker with the current PDP or current basket products (e.g.: same brand, same category, ...)
Product Attribute Value Retargeting : personalize on the prior product views of the visitor (most of the time should be a Scorer)
Promote purchased items & Attribute Values : personalize on the prior product purchases of the visitor (most of the time should be a Scorer)
